I have a three jaw chuck that came with my South Bend 14.5" lathe. I also have a four jaw but the back plate was threaded for a different spindle. I am brand new to machining but still attempted to bore and rethread the backplate 2-1/4 and 6 tpi. The boring was the easy part but I failed miserably cutting the internal threads and ruined the piece.
Now I am looking for a backplate. Is my best option to try again or does someone have an old back plate laying around? Best source for a semi finished back plate?
My existing, ruined, back plate is about 6" in diameter and about 1-1/2" thick.
Thanks in advance for your help.
